-= EdgeCase Ruby Koans
-
-The Ruby Koans walk you along the path to enlightenment in order to learn Ruby. 
-The goal is to learn the Ruby language, syntax, structure, and some common 
-functions and libraries. We also teach you culture. Testing is not just something we
-pay lip service to, but something we live.  It is essential in your quest to learn 
-and do great things in the language.  
-
-== The Structure
-
-The koans are broken out into areas by file, hashes are covered in about_hashes.rb, 
-modules are introduced in about_modules.rb, etc.  They are presented in order in the 
-path_to_enlightenment.rb file.  
-
-Each koan builds up your knowledge of Ruby and builds upon itself.  It will stop at 
-the first place you need to correct.  
-
-Some koans simply need to have the correct answer substituted for an incorrect one. 
-Some, however, require you to supply your own answer.  If you see the method __ (a 
-double underscore) listed, it is a hint to you to supply your own code in order to 
-make it work correctly.  
-
-
-== The Path To Enlightenment
-
-In order to achieve enlightenment you need to follow the path_to_enlightenment. This
-can be done in two ways
-
-*nix platforms, from the koans directory
-
-    [koans] $ rake                              # runs the default target :walk_the_path
-    [koans] $ ruby path_to_enlightenment.rb     # simply call the file directly
-    
-Windows is the same thing
-
-    c:\dev\koans\rake                           # runs the default target :walk_the_path
-    c:\dev\koans\ruby path_to_enlightenment.rb  # simply call the file directly
